Photo of a two-story single-family home shaken on an indoor shake table at the State University of New York at Buffalo.

The benchmark NEESWood structure, a two-story, single-family home, was shaken on an indoor "shake table" at the State University of New York at Buffalo. The shake table is part of NSF's Network for Earthquake Engineering Simulation (NEES). The test revealed that wood-frame structures, constructed under current building standards, may provide safety in an earthquake similar to the 1994 Northridge earthquake in California, but the structures are likely to be damaged so severely that they will require expensive repairs.
